简单的波束形成，方便初学者多数字波束形成有个简单的了解，通过加切比雪夫窗实现旁瓣与主瓣的db差-Simple beamforming, easy for beginners and more digital beamforming is a simple to understand, Gache achieved by the main lobe and sidelobes Chebyshev window db difference

当有噪声时，数字波束形成仍可以将来自不同方向的信号进行分辨，要注意噪声的大小影响波束的形成-When there is noise, digital beamforming signals can still be distinguished from different directions, to pay attention to the size of the impact beam is formed of the noise

在数字波束形成过程中，利用旁瓣对消技术，可以很好的控制波束-In the digital beam forming process, using sidelobe cancellation technology, can be well controlled beam

在数字波束形成中，利用零点约束可以很好的控制波束形成，方便初学者使用-In digital beamforming using zero constraints can be well controlled beam forming, easy for beginners to use
